IMPROVEMENT IN DITCHING AND TILE-LAYING.

Specification forming part of Letters Patent No. 188,778, dated March27, 1877; application filed August 23, 1876.

To all whom it may concern:

Be it known that I, T. G. GOIL, of Washington Court-House, in the countyof Fayette and State of Ohio, have invented a new and .usefulImprovement in Making a Tile Ditch and Laying Tile, as will be fully setforth in the following specification.

Figure 1 is a perspective of my invention. Fig. 2 shows the staple forbinding the tiles together. Fig. 3 is the break-detecter.

A represents the vertical beam, which has a sharpened edge for cuttingits way through the earth, as it is drawn along by the capstan or othersuitable power. To its lower end is secured'the mold B, which opens thefurrow for the tiles. Fastened to its rear end is a solid casting, G,shaped somewhat like the tiles D, that follow on behind, the tiles beingfastened to this mold and to each other by means of the staples a.

Very frequently a break occurs in the line of tiles, and as there is noway of finding out just where it is a break-detector has to be employed,or the machine will be found impracticable. For this purpose emply therods E, each one of which is of a known length, and

which are united together by the couplingnuts F. To the front end ofthese rods is screwed the solid casting G. When a break occurs, thiscasting G is inserted into the orifice of the tile, and pushed alongdown into it, rod after rod being screwed together, as may be foundnecessary. When the casting reaches the break it falls into the openingcaused by the separation of the tiles, and then cannot be pushed forwardor backward. By knowing the number of rods pushed into the tiles and thelength of each one, the exact place where the break is is at once known.A hole is then dug down to the tiles, the break mended, the hole coveredup, and the ditch completed.

Having thus described my invention, 1 claim- As an improvement inditching and tilelaying, the combination of the rods E, nuts F, andcasting G, for finding the breaks, substantially as shown.
